6914600, Jul 5, 2005

Filed:

Jun 26, 2001

Appl. No.:

09/893146

Inventors:

Thomas Malzbender - Palo Alto CA, US
Gregory Gilbran Slabaugh - Atlanta GA, US
William Bruce Culbertson - Palo Alto CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06T017/00

US Classification:

345424

Abstract:

A method of generating a three-dimensional model of a scene from a plurality of photographs of the scene. The method includes voxels in an interior region and an exterior region of the scene in question and then examines the voxels to determine if they are empty or part of the objects in the scene. The interior region is divided into a plurality of interior voxels, that are preferably of the same size. The exterior region surrounds the interior space and is divided into exterior voxels having different sizes. The size of the exterior voxels increases as a function of the distance between the voxel and the interior region. The voxels that are furthest from the interior region are preferably infinite in size.

Appl. No.:

13/023483

OPTIMEDICA CORPORATION - Santa Clara CA

International Classification:

A61B 18/20

US Classification:

606 6

Abstract:

A system for cataract surgery on an eye of a patient is described. In one embodiment, the system comprises a first laser source configured to deliver a first laser beam in a pulsed form at a first pulse energy; a second laser source configured to deliver a second laser beam in a pulsed form at a second pulse energy greater than the first pulse energy; an scanning optical system, configured to: receive the first and second laser beams; and adjust a first focus position of the first laser beam, and a second focus position of the second laser beam, in up to three dimensions to direct the first and second laser beams onto one or more targeted tissue structure portions of the eye of the patient; a controller operatively coupled to the scanning optical system and configured to cause the scanning optical system to adjust the first focus position to photodisrupt a first tissue structure portion with the first laser beam, and subsequently adjust the second focus position to further photodisrupt the first tissue structure portion with the second laser beam.

Georg Schuele - Menlo Park CA, US
Dan Andersen - Menlo Park CA, US

Assignee:

OPTIMEDICA CORPORATION - Santa Clara CA

International Classification:

A61F 9/008

Abstract:

A method for cataract surgery on an eye of a patient includes scanning a first focus position of a first pulsed laser beam at a first pulse energy of between one-half microjoule and 50 microjoules in a first scanning pattern to photodisrupt a first tissue structure portion with a plurality of pulses of the first laser beam to form an incised surface; and afterwards, scanning a second focus position of a second pulsed laser beam having a second pulse energy being between 50 microjoules and 5,000 microjoules in a second scanning pattern that is co-registered to the first scanning pattern to further photodisrupt the same first tissue structure portion with the second laser beam to further separate segments of the first tissue structure along the incised surface.
